UNITED STATES JAMES G. MCNAMARA, OF BROOKLYN, NEWVYORK, ASSIGNOR TO y MERGENTHALER TYPoGRArHroAL MACHINE.

Application ined Mayra, i924. serial No. 714,214; y

This invention relates to typographical machines, such as linotype machines of the general organization represented in the Mergenthaler Patent No. 436,532, wherein circulating matrices are released from a machine by suitable escapementdevices in the order in which their characters "are to appear in print, and then assembled in line, the composed line transferredv to the face of a mold, the mold illed with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started. More particularly, it relates to that class of machines equipped `With a plurality of magazines mounted in a so-called shift frame, which is movable rectilinearly to bring anyl selected magazine into operative relation to the assembling and distributing devices. In the commercial machines, the magazines are supported in parallel spaced relation upon separate. base frames pivoted at their upper ends and resting upon oney another at their lower ends, means being provided for spreadingl the basel frames apart to permit the independent removal of the magazines. l

The present invention is'directed toy certain improvements in machines of the class stated and contemplates which Will permit the ready removal of the magazines, and this Without having ito spread'them apart prior to removal; The exact nature of the improvements will best be understood from the detailed description to follow.

Referring to the drawings Fig. l is a side elevation of the upper portion of a linotype machine equipped with the resent improvements, the dotted line position showing the magazines elevated for front removal;

Fig. 2 is a plan view of one of the base frames and the associated parts; f

Fig. 3 is a detail perspective of the escapef ment bar; and l Fig. l is an enlarged vertical section rtaken through the magazine structure and showing three positions of the means employed to permit the removal of escapementbar and magazine.

a construction The matrices X are stored according to font in the super-posed'channeled magazines A, three of which are shown herein, but ot which a greater number might be employed,

vif desired. y The several" magazines A are mounted upon separate base trames A1 carn ried by a bottom supporting frame A3, Which is arranged to be moved upwardly and downwardly to bring any selected magazine into operative relationto the assembler entrance B and magazine entrance F1, the latter leading from the distributor l?. iEach of the magazines A is provided with matrix releasing escapements c, Which, When the `magazine 1s in use, are actuated through the medium of pivoted levers C1 by reeds C2, controlled inthe usual Way from a keyboard (not shown). The escapements ol each magazine are, as usual, mounted in a supporting bar or trame C (Fig. 3), which maybe engaged with or disengaged from the magazine at Will. The supporting frame A3 is attached to a sliding plunger L (see. Fig. l), adapted tobe raised and lowered Within a lixedsleeve O by the Wellknovvnscrew thread mechanism usually enr ployed in lmachines of this character. In

`order to guide the magazine supporting frame A3 iny its rectilinear movements, itis provided With the perpendicular members A4,- arranged on opposite sides and near the upper end thereof, and having sliding engagement With supplementary brackets O2,

secured to the inner faces of the main distributor bracket O1. Registering and locating means .for the magazines are also provided, such means comprising y (see Fig; l) a pair of bars D1, movably arranged on opposite sides of the machine and adapted to cooperate With lugs D protruding from the sides of each of the kbase trames A1. These bars are looselyconnected to the upper ends of apair ot' larms D2, fastened to a rock shaft D3, which is actuated 'from the front of the ymachine against the tension off a spring D4, the latter tending to keep the bars in their active positions. The parts so far described, except as hereinafter Vpointed out, are or may be the same as those y.embodied in the commercial Model 8 linotype, or as shown and described in the Rogersy Patent No. 1,109,872, to which reference may n be had, desired.

According to the present invention, the magazine base frames A1 are secured to the bottom supporting frame A3 by clamping bolts of, which pass through spacing blocks or gauge pieces A5, AG, protruding from opposite sides of said frames at their upper and lower ends. The proper positioning of the base frames is taken care of by means of two pairs of set screws 61,1, a?, the former arranged in the perpendicular members A and extending inwardly therefrom to engage the side faces of said frames, and the latter passing through the gauge pieces A6 and engaging the rear edges of said perpendicular members (Fig. 2.) In this way, the base frames are made capable of independent adjustment, both laterally and longitudinally, before they are fastened down upon the bottom supporting frame. A3, the bolt apertures in the spacing blocks A5, A being sutliciently enlarged for the purpose. A rigid composite shift frame comprising a bottom supporting frame and a plurality of subsidiary magazine frames is thus provided, although as will later be seen, the magazines are capable of being removed independently in the desired manner. 1t may also be noted that the construction is such that the shift frame may be built up to accommodate any desired number of magazines simply by the employment of the requisite number of base rrames.

Since the magazine shift frame is in the nature of a rigid structure, the locating bars Dl are made capable of vertical adjustment, in order to insure registration of the magazines with the assembling and distributing devices. Accordingly, the bars are mounted in adjustable front and rear brackets O3 and @4. Set screws G5 serve as a verticalA support for the rear brackets O4 and clamping screws OG serve to fasten them in place against the inner faces of the distributor bracket O1. The front brackets 0"" are similarly provided with supporting set screws OT and clamping screws OS.

lt has been the common practice in machines of this class either to pivot the escapement bars to the base frames, so that they may be lowered out of the way to facilitate the removal of the magazines, or to mount them in the shift frame in some such manner as shown in the Rogers patent before mentioned. In the present instance, however, the escapementbars are mounted upon and carried by the base frames A1 and in such manner that they may be removed endwise therefrom preparatory to the removal of the magazines. Accordingly, the base frames A1 are provided with plates A7 fastened to and extending forwardly from the underside thereof to support the escapement bars, the latter being held in place by tongue and groove connections AS, A9, which permit their ready endwise removal. In order to facilitate such removal of the escapement bars, means are provided for first breaking the operative engagement between them and the magazines.

vided at one end with a small hand crank G3. As shown, the rock shaft is cut away or recessed as at g, g to receive and support the retaining member at two different lower levels. lVith this arrangement, it will be seen that by turning the associated hand crank G3, any magazine may be raised clear of the corresponding escapement bar to allow the latter to be withdrawn endwise in the manner stated (see Figs. 2 and t.)

As illustrated in Fig. 4, the customary removable rod l) is employed to lock the matrices in the magazine before its disengagement from the escapement bar. ln the present instance, the rod is also employed, when shifted from its position within the magazine to that shown in the drawings, to lock the magazine retaining member G against upward movement. ln other words, the escapement bar is grooved, as at E, to receive the rod P, in such position that the latter engages the end of the member G and thereby prevents rotation of the rock shaft G2 and the consequent raising of the magazine. In this way, the premature disengagement of the magazine from the escapement bar is prevented.

The manner in which the magazines are removed will now be clear: In Fig. -,the rock shafts G2 and the magazine retaining members G are shown in three different positions, designated fr, r/ and .2, respectively. `When a rock shaft is turned from position ai to position g/ by means of its small hand crank G3, the member G is cammed upwardly far enough to raise the magazine clear of the escapement bar C, which latter (shown in dotted lines) is then free to be removed endwise in the desired manner. Then the rock shaft is later turned from position g/ to position s, the men'iber G drops into the recess g and carries its retaining lip G1 out of the way of the magazine, which may then be slid forwardlyin its own plane from the base frame for removal. A pair of supporting arms R (see dotted lines, Fig. 1) may be employed to assist the operator in removing the magazine and substituting another. After a substituted magazine has been placed upon the base frame, the rock shaft is turned back to position g/ and lifts the retaining member G into engagement With the magazine. The escapement bar C is then reinserted and pushed home against an adjustable stop A10 (Fig. 2). The rock shaft is thereafter turned to its original osition z and brings its recess g into position to receive the member Gr, thus permitting the magazine to be lowered into operative engagement with the escapen'ient bar. It desired, the escapement bar may be provided, 'for registration purposes, with the ordinary locating tooth m (Fig. 3), Which is adapted to engage a corresponding notch in the magazine. The matrix locking rod P may now be withdrawn with safety from the magazine and reinserted in the escapement bar to function in the manner before described.

In thevaccompanying drawings, the improvements have been shown merely in prejierred form and by way of example and, ob-

viously, many changes and variations may be made therein and in their mode ot application, which will still be comprised Within the spirit of the, invention.
